Product description
This E-Bike is a perfect choice if you desire a versatile riding experience suitable for riding both flat
and hilly terrain.
The frame is made from aluminium, which ensures a stiff, robust, and lightweight construction.
The drive unit is centrally placed by the bike’s crank, and the battery is either integrated into the
downtube or the rear carrier depending on the model. This way the weight is distributed optimally.
The E-Bike also works as a regular bike.
The buttons for the electronic system have been designed and developed ergonomically to ensure
ease of use.
Get started
After the battery is installed, switch on the on/off button. You step on the pedals and the drive unit
starts to help you, depending on which assist level you have chosen.
See further details under section 4.
The bike, or its components, can be destroyed or damaged if you ride in a way that is
more stressful than the way the bike was designed for. If the bike is damaged, you
may lose control and crash. Do not exceed the limitations of the bike’s design. If you
are not sure about the bike restrictions, please ask your dealer.
As with all mechanical components, the bike is exposed. Different materials and com-
ponents can react in different ways. If a component’s lifespan is exceeded or over-
loaded, it can suddenly cause injury to the cyclist. If some kind of cracks, scratches or
changes in color appear, it may be a sign that the component is overloaded and there-
fore needs to be replaced.
WARNING

7
Handlebar
The angle and height of the handlebars are adjusted as follows:
Change the angle and height by opening the handle on the stem, then adjust the handlebar to the
desired position. Lock the setting by pressing the lever down again.
Saddle
The saddle height must suit the rider of the bike. The saddle must not be set higher than the
maximum marking on the seat post.
Brakes
It is important that you learn how the brakes work. Make sure you can reach the brake lever to the
front brake, which is activated by the left brake lever. Use both brakes moderately for optimum
braking effect.
Gearing
The gearing is controlled by using the shifters on the right and left side of the handlebar (on some
models). Remember to stop pedaling, when you shift gears.
NOTICE
• Change gears as you would on a normal bike. By setting off in a lower gear, the chain and
sprocket will last significantly longer than if, for example, you set off in a high gear.
Adjustments before use

8
To adjust the chain, loosen the hub nuts and the bolt in the rear hub brake arm. Then move the rear
wheel forward or backward so that the chain gets the desired clearance. Remember to tighten the
hub nuts and the brake arm bolt and check that the wheel sits right in the middle of the rear fork.
Chains on bicycles with external gears (derailleur gear)
The chain is automatically tensioned by the chain guide arm of the gear. If the chain needs to be
changed, it is recommended to contact your bicycle dealer, as the chain must have the correct
length and often the chain and sprocket must be changed at the same time.

For your own safety and to maintain the right to claim, it is important that the bicycle is maintained.
Good maintenance makes cycling more enjoyable, and the bike will last longer. We therefore
recommend reading the instructions thoroughly.
Many people can handle most of the maintenance themselves, but bicycles are often equipped
with complicated fine mechanics, which we would advise to have serviced and maintained at the
bicycle dealer.
This manual provides tips and guidance on components and parts that require special
attention.
The chain
All chains - also stainless - must be regularly wiped, lubricated and adjusted. A clean and well-
maintained chain provides greater riding joy, the risk of breakage is reduced and the load on the
gear and hub is minimized.
Chains on bicycles with internal gears (hub gears)
It is important to ensure that the chain is correctly tensioned. At the center of the free length of the
chain, the clearance up and down must be a maximum of 20 mm. On the other hand, the chain
must not be too tight, as a chain that is too tight can cause damage to the rear wheel bearings.

Bolts and screws
When riding the bicycle, vibrations occur, which can loosen bolts and screws. Therefore, the bicy-
cle should be regularly checked and loose parts tightened.
Do not use excessive torques. The tightening torque must be adapted to the dimension of the
screw assembly. If it is too tight, there is a risk that the screw will come off or the thread will be
damaged.
The following tightening torques are indicative for standard bicycles, but can vary greatly depen-
ding on the material the frame and component are made of:
Crankshaft pin 35 - 55 Nm
Lock nut on steering bearing 25-35 Nm
Front wheel hub nuts 20-30 Nm
Rear wheel hub nuts 30-45Nm
Expander bolt in stem 15 Nm
Seat post 7 Nm
Saddle 20 Nm
If in doubt, you should leave the work to your bicycle dealer, as incorrect tightening torque can
cause damage to the frame and components and, in the worst case, lead to accidents.
Cables
All cables should be kept well lubricated. Regularly check the cables for breaks or wear on the
wire, so that bursting of the cable is prevented.
Important: It is important for safety to have the bike dealer blow all cables clean of condensation
and lubricate them before the winter period with a silicone-based grease. This minimizes the risk of
the cables freezing.

10
Brakes are an important part of the safety of a bicycle. Therefore, all types of brakes must be regu-
larly checked and adjusted to ensure that they work optimally. Be aware that most of the braking
power comes from the front wheel. Therefore, use the front brake with caution and preferably to-
gether with the rear brake to avoid accidents.
On fully hydraulic disc brakes, it is important to check the durability of the fluid/oil in the brake
system. Condensation can occur in the system, which means reduced braking performance. In this
case, the fluid/oil must be changed. For safety reasons, service is therefore recommended once a
year or according to the manufacturer’s instructions. As it requires great insight and professional
ability to carry out the necessary service, it must be carried out by the bicycle dealer.

There are basically two types of gears. Hub gears (internal) and derailleur gears (external). Com-
mon to both gear types is that they require correct adjustment, lubrication and regular maintenance
in order to function optimally.
Hub gears
It is important for the life of the gear that the gears are adjusted correctly. Contact the bicycle deal-
er immediately if it is found that the gear does not work perfectly. Driving for too long with an incor-
rectly adjusted gear can damage the hub.
Due to the climatic conditions in Denmark, it is important, regardless of what the gear manufacturer
states, that the gear hub is disassembled, cleaned and lubricated at least once a year.
If the hub is exposed to salt water, it must be disassembled, cleaned and lubricated immediately to
prevent corrosion damage that could render the hub unusable.
Disassembly, cleaning and lubrication must be carried out by a specialist.
If the bicycle is cleaned with water, it is important to ensure that the water does not penetrate the
gear hub. Never use high-pressure cleaners/washers.

External gears (derailleur gears)
The derailleur gear system must always be cleaned of dirt and grime and be well cared for in order
to function. It is normal for the chain and rear sprocket to be changed every approx. 3,000 km or
minimum every two years - and more often if said maintenance is not observed. Since the chain
and rear sprocket wear together, you should always replace both parts at the same time.
Note that the rear derailleur must be correctly adjusted, i.e. the two chain guide wheels parallel to
that of the cassette, and never beyond the two outermost gears. If the rear derailleur or the fork
end is pushed inwards (the bike may, for example, have fallen over without you knowing it), the de-
railleur can go into the spokes of the rear wheel, with major damage as a result.
Like the other parts of the gear system, the freewheel/cassette housing must be lubricated regular-
ly. If the bike is not used for an extended period, the freewheel/cassette hub must be particularly
well lubricated. Dismantling the freewheel/cassette hub requires special tools and should be car-
ried out by a specialist.
When cleaning, do not use high-pressure cleaners/washers.
Only shift gears when pedalling forward. Changing gears when pedalling backwards can cause se-
rious damage on the gear system.

Crank and head sets (bearings) must be well lubricated and move easily and without play. If there
is a play, it must be corrected, otherwise bearings and other parts such as e.g. fork tube thread
may be damaged.
Play must be corrected by the bicycle dealer.
Crank and head sets

13
Spokes
Spokes will give when using the bike. It is therefore important that the spokes are regularly inspect-
ed to ascertain whether they are properly tensioned and none are loose. If a spoke pops, it must be
changed immediately and the rest of the spokes must be adjusted and tightened. If you drive with a
cracked spoke, it will usually result in the wheel breaking and a replacement of both rim and spoke
may prove necessary.
Since re-tensioning and replacement of rims or cracked spokes require specialist knowledge, the
maintenance must be carried out by the bicycle dealer.
Quick release
Some bicycle types have quick release hubs. This means that the wheels can be removed and in-
stalled using the eccentric quick-release arm on one side.
It is important that the wheel is clamped correctly and with the right force. With correct locking, re-
sistance can only be felt when the arm is half locked. If too much force must be applied, loosen the
nut on the other side slightly and try again. Please note that if too much pressure is applied to get
into the locked position, the inner shaft can be subjected to such great pressure that it breaks.
If in doubt, contact your dealer.
Wheels and spokes

14
Suspension forks are available with many different damping systems, each of which requires its
own form of maintenance.
Basic suspension fork maintenance is to ensure that the upper parts of the inner fork legs are clean
and free of sand, gravel or other debris. Chrome-plated inner legs must be maintained with a
chrome care product.
Please note that a suspension fork requires special care, and in order to function satisfactorily, it
must be serviced at least once a year or more frequently depending on the manufacturer’s instruc-
tions. Remember to check the service intervals.
A simple fork, which only contains a steel spring, does not require much maintenance, while more
sophisticated forks are sensitive to the condensation that forms in all forks and should therefore be
disassembled, lubricated and have the oil changed after 50 - 100 hours of use.
As it requires a great deal of insight and professional skill to carry out the necessary service, it is
recommended to have the bicycle dealer carry it out.

Tires
Always keep the tires inflated to the correct tire pressure. It makes driving easier and prevents
damage to tires, tubes and rims.
The correct tire pressure is indicated on the side of the tyre, e.g. as INFLATED TO 40 -65 psi or
max. 60 psi. If you don’t have a pump with a tire pressure gauge, the pressure can be checked by
pressing your thumbs hard against the tire. The tire should feel hard.
It is recommended to check the tires before riding for correct pressure and to remove stones that
have become stuck. This avoids many punctures.
Tubes
Bicycle tubes can be fitted with different valves. Atom, Presta and Schrader valves.
Please note that when pumping tubes with a Presta valve, the small nut on the valve must be
loosened before pumping. If this does not happen, air will not enter the tube, and you risk breaking
the valve with the pump.

Stone chips and scratches should be repaired as soon as possible after they occur. Otherwise, rust
formations can occur, which in the worst case can spread and “run” under the paint.
Keep the lock clean and free of dirt. Lubricate the cylinder, trigger and locking arm opening regular-
ly. Open and close the lock repeatedly after lubrication.
In order to get a saddle as comfortable as possible, it is important to make sure that the distance
between the cushions (resting points) on the saddle corresponds to the distance between the seat
bones. Ask your dealer for help to find the correct saddle.
Saddles in core leather must be maintained with leather grease so that flexibility is optimal at all
times. The core leather will give with use and it is therefore necessary to tighten the leather by ad-
justing the adjusting screw under the nose of the saddle. Always follow the saddle manufacturer’s
instructions for correct maintenance.
Plastic saddles can be advantageously sprayed with “Plastic Finish” to freshen up the surface and
make it continue to be water resistant.
If you have had an accident, been knocked over, hit, etc, whereby the handlebar, frame, front fork,
pedals, or crank arms may have been damaged, replacement should always take place, as the
danger of subsequent breakage is present.
Always keep the bike clean. Use regular cleaning detergents and a soft brush to remove dirt. The
dealer has a wide selection of environmentally friendly lubricants and care products and is happy to
advise on the general care of the bicycle. Regular cleaning extends the life of the bicycle.
If your new E-bike is equipped with an approved lock, 2 keys are included. As there is no register
that can tell which key is fitted to which bike, it is important to save the issued lock certificate on
which the key number is listed. It must be used when you want to buy extra keys for the lock.
Extra keys can be bought from your dealer.

In the vast majority of areas, an E-bike looks like a normal bicycle and must be maintained in the
same way and at the same intervals.
Manufacturer’s references
It is very important to read the manufacturer’s instruction manual thoroughly and to follow the ser-
vice intervals and the instructions given on charging the battery and maintaining the various com-
ponents.
The instruction manual also contains important information about special complaint provisions re-
garding the E-bike.
If the bicycle is not used for a long period, e.g. during a severe winter, it must be protected from
rust. Spray chrome-plated and galvanized parts and details with an anti-rust agent. Places on the
frame where it is difficult to get to and aluminum parts are protected against rust and oxidation.
It is a good idea to store the bike hanging. This relieves the tires and they are less prone to
cracking.
When the bicycle is put into use again, it must be thoroughly dried. If the bicycle is equipped with
rim brakes, it is particularly important to thoroughly wipe the rim sides to maintain optimal and safe
braking performance.
It is a good idea to talk to your insurance company to learn how your bicycle is covered.
